cds-question@unistra.frasteroseismologygiant-starsstellar-masseschemical-abundancesWe present measurements of the dipole mode asymptotic period spacing ({Delta}{Pi}1), the coupling factor between the p- and g-modes (q), the g-mode phase offset ({epsilon}g), and the mixed-mode frequency rotational splitting ({delta}{nu}rot) for 1074 low-luminosity red giants from the Kepler mission. Using oscillation mode frequencies extracted from each star, we apply Bayesian optimization to estimate {Delta}{Pi}1 from the power spectrum of the stretched-period spectrum and to perform the subsequent forward modeling of the mixed-mode frequencies. With our measurements, we show that the mode coupling factor q shows significant anticorrelation with both the stellar mass and metallicity, and can reveal highly metal-poor stars. We present the evolution of {epsilon}g up the lower giant branch up to before the luminosity bump, and find no significant trends in {epsilon}g or {delta}{nu}rot with the stellar mass and metallicity in our sample. Additionally, we identify six new red giants showing anomalous distortions in their g-mode pattern.2023ApJ...954..152Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/954/152CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)III/286 : APOGEE-2 DR17 final allStar catalog (Abdurro'uf+, 2022)J/A+A/540/A143 : Oscillations of red giants with Kepler (Mosser+, 2012)J/ApJ/765/L41 : Asteroseismic classification of KIC objects (Stello+, 2013)J/A+A/572/L5 : Evol. state of red giants from seismology (Mosser+, 2014)J/A+A/588/A87 : Seismic global parameters of 6111 KIC (Vrard+, 2016)J/MNRAS/466/3344 : Red-giant stars classification (Elsworth+, 2017)J/MNRAS/469/4578 : Deep learning classif. in asteroseismology (Hon+, 2017)J/A+A/600/A1 : Coupling factors of 5166 KIC (Mosser+, 2017)J/A+A/616/A24 : Rotation in RGBs from Kepler asteroseismology (Gehan+, 2018)J/MNRAS/476/3233 : 14983 Kepler red giants (Hon+, 2018)J/A+A/618/A109 : Seismic global parameters of 372 KIC (Mosser+, 2018)J/ApJS/236/42 : Asteroseismology of ~16000 Kepler red giants (Yu+, 2018)J/MNRAS/489/4641 : APOKASC Evol. state of red-giant stars (Elsworth+, 2019)J/MNRAS/488/572 : Bayesian hierarchical inclinations (Kuszlewicz+, 2019)J/ApJ/887/203 : Core rot. period measurements of KIC stars (Tayar+, 2019)J/A+A/645/A124 : Inclinations for RGBs from Kepler (Gehan+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/954/152https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/954/152http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/954/152https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/954/152https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/954/152http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/954/152GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/954/152/table1 (Mixed-mode parameters of 1068 Kepler red giants from the Gehan+ 2018, J/A+A/616/A24 sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/954/152/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/954/152/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/954/152/table1?GETtext/xml+votable180.050000true291.334209736.78661470.0055555555555555564/922-923 933-935 944-945 5/3645-3646 3683 3704 3706 3729-3731 3760 3784-3786 3789 3792 6/14567 14573 14575 14578-14579 14588-14589 14591 14730-14731 14744 14746-14747 14750-14751 14792 14794-14795 14822 14828 14830-14831 14914-14915 15044-15045 15057 15059-15062 15148-15150 15153-15155 15160 15172-15174 15178 15200 15232https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/954/152?format=asciidefaultJ/ApJ/954/152/table1Mixed-mode parameters of 1068 Kepler red giants from the Gehan+ 2018, J/A+A/616/A24 samplerecnoRecord number assigned by the VizieR team.
